BATHTUB WASTE-FITTING.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed August 4, 1916. Serial No. 113,061.

To all whom it may concern Be it known that 1, JOSEPH 1V. SHARP, Jr., a citizen of the United States, residing at Berwyn, in the county of Chester, State of Pennsylvania, have invented a new and useful Bathtub lVasteFitting, of which the following is a specification.

The invention relates to improvements in bath tub fittings. The object is to provide improved means for forming and assembling the componentparts of the waste piping, improved means for actuating the valve and improved means for forming, assembling, adjusting and operating said actuating means.

The improved mechanism applies especially to structures where the tub is built into the wall or partially built into the wall and the fixtures are concealed either in or behind the wall and in the floor.

The invention is an improvement on the structure shown in Patent No. 843,968, granted me February 12, 1907. It comprises means for'meeting the requirements of the modern practice of installation, especially where the tubs are tiled into the floor,

or wall, or both.

Referring to the drawings, which illustrate merely by way of example, suitable embodiments of my invention:

Figure 1 is a vertical section showing my improved structure.

Fig. 2 is a detail in elevation showing the valve and the actuating rod engaging therewith. i

Fig. 3 is a view in plan of the split cap 22.

Similar numerals refer to similar parts throughout the several views.

The waste piping comprises the horizontal extension 3, the elbow 4 forming a housing for the valve seat section 5 and valve 6, which housing is connected in the bottom of the tub 7. The horizontal section 3 is connected at its right hand end with the vertical extension 8, which is connected at its lower end 9 with the pipe 10. The upper end of extension 8 is slightly bored out, as at 11, leaving a projecting shoulder 12. This bored out section 11 is adapted to receive the spider 13, which rests upon the shoulder 12 and forms a guide for the upwardly extending portion 1 1 of the actuating rod.

The bored out portion 11, of pipe exten sion 8 also receives the lower end of pipe extension 15, which rests upon the top of spider 13. The collar or sleeve 16 has threaded engagement with the upper end of pipe extension 8, surrounds pipe 15, and compresses the gasket 16, so as to form a water tight oint between pipes 8 and 15.

The upper end of pipe 15 has a sliding fit 1n the lower end of the hollow body 17, which is provided with a nearly horizontal extending portion 18, which forms the up-- per overflow portion of the waste and is connected with the tub 7 and held in place by the threaded engagement with the flanged member 19. The body 17 is also provided with the inner annular portion 20, which has an interior thread for receiving the upper threaded end of the short tube 21. This tube 21 is spaced away from the sides of the upper end of tube 15 and forms an apron to carry the water beyond the joint between upper end of tube 15 and body 17.

At the upper end of body 17 is provided the split collar or cap 22, which surrounds the upper end of rod let and is threaded into the upper end of body 17.

The upper end of rod 1 1 is provided with a head 23, which is preferably upset thereon.

A swivel nut 24: surrounds this head and has threaded engagement with the interiorly threaded sleeve 25, so that said threaded sleeve 25 may be freely turned independently of the rod 14:. The top end of threaded sleeve 25 receives the lower end of thread ed vertical extension 26, which is connected with the horizontal extension 27 and the vertical upwardly extending portion 28.

This upwardly extending portion 28 is secured by any suitable means with the eccentric 29 on shaft 30, which is operated by the handle 31, so that by turning handle 31 in one direction or the other, as the case may be, the extension 28 and the rod 14 are raised or lowered. The lower horizontal extension of rod 14 passes beneath a notch of the extension 32 of valve member 6, so that when the rod 14 is lifted by operating handle 31, the valve 6 is lifted from its seat.

It is now becoming a common practice to set the tub directly on the floor, that is without using supporting legs therefor. In this case it is necessary, especially where tile and cement are used in forming the floors, to place the lower part of the waste in the floor, that is embedded in the concrete, at the time the tub is put into position, and it has thus become desirable that the part of the waste structure which is embedded in the floor at the time of setting the tub, should the corresponding portion of the actuating rod 1 L, that is to say the part ending at the threaded sleeve 33. In place of the collar or nut 16, a solid cap is also furnished to protect the interior parts during the roughing in, so that when this operation is com pleted, the cap may be removed and the upper vertical extension of rod 14:, may be screwed the required distance into the threaded sleeve 38 and then looked into the required position of adjustment by the set screw 84.

A further adjustment with respect to the throw of the eccentric 29 and the open and closed positions of valve 6, that is to say, the

distance between the axis of stud 29 for example, and the axis of lower extension of rod 14, is secured, by turning the threaded sleeve 25. This sleeve 25 has a swivel connection with the upper end of rod 14. The upper rod section and sleeve are then locked into required position of adjustment by means of the set screw 35. the horizontal extension 27 of the actuating rod, secures the required ofi'set between the vertical plane of the extension 28 or the eccentric member, and the vertical plane of the actuating rod l l, depending upon the thickness of the wall or other structure which must be interposed between the actuating handle 81 and the said eccentric.

It will be obvious that the sleeve 83 and the sleeve 25 and swiveling nut 24: will greatly facilitate the assembling of the sevoral portions of the actuating rod.

It will also be understood that the spider 13 forms a useful guide for lower portion of the vertical part of the rod 1 serving not only to keep the said part-s in place during the roughing in but facilitates the assembling with the balance of the rod 14, and

The length of affords a sufficient guide way during the actuation of said rod.

What I claim is 1. In a bath tub waste fitting, the combination of a waste valve, a piping connected therewith, having partly horizontal and partly vertical extensions, a valve actuating rod within the piping having corresponding partly vertical and partly horizontal extensions, said piping and said rod being in sections and separable in their vertical extensions at a point approximately in the plane of the waste valve, and a removable rod supporting and centering means within the piping beneath but near said point of pipe separation.

2. In a bath tub waste fitting, the combination of a waste valve, piping connected therewith having partly horizontal and partly vertical extensions, a valve actuating rod within the piping having corresponding partly vertical and partly horizontal extensions, said rod being extended above the piping and provided exteriorly of the same with a head, an exterior swivel nut receiving and engaging the head to form a swivel, a sleeve having a threaded connection with the swivel nut, operating means, a rod section connected with the operating means and threaded into the sleeve which forms an ad- I justable connection between the rod section and the valve actuating-rod.

3. A bath tub waste fitting comprising a piping having a horizontally extending portion and a vertically extending portion and a valve actuating rod comprising disengageably connected sections, one of said rod sections having a horizontal extension between two vertical offset extensions.

A. A bath tub waste fitting comprising a piping having a horizontally extending portion and a vertically extending portion, a valve actuating rod comprising disengageably connected sections, one of said rod sections having a horizontal extension between two vertical ofi'set extensions, and rod actuating means comprising an operating handle projecting from the wall above the tub and a shaft extending therefrom through the wall or covering tile, to-an eccentric engaging the upper vertical ofiset extension.
